? I mean, the junk in website.make from lines 67 to 71 (inclusive), and 77
to 81, is what defines the actual command-line. Could somebody figure out
the EXACT command-line which gets called for one of the cases where we see
a bunch of warnings?

I think there's an option you can give to make... maybe -n ...? which
forces it to print extra information. That might helpful here, instead of
just manually looking at variables in website.make.
